Abstract
An optics of a read/write system includes a stationary optical device for condensing a light beam and leading said light beam into an optical fiber. A distal end of the optical fiber is moveable and with a tapered configuration thereof for focusing the light emerging from the optical fiber into a beam spot on an optical recording medium. A detector detects through the optical fiber light reflected back from the recording medium.
